verify
Grades work for merge: runs unit, integration and E2E suites plus security and type checks, scores 0-10 with a VERIFIED vs CLAIMED manifest. Use when deciding if work can ship. Not for adding missing tests (use cover).
Why this skill is useful
Adds a comprehensive verification framework with parallel agents and scoring mechanisms that aren't available in standard testing practices.

What this skill does
Verify Feature Host-neutral workflow. Invoke by skill name (verify). Claude Code slash routing, YAML hook loaders, and .claude/chain live in references/claude-code.md. Comprehensive verification using parallel specialized agents with nuanced grading (0-10 scale) and improvement suggestions. Quick Start Argument Resolution A pronoun target (this, them, the above) is read back from the conversation, announced in one line, and used: Read("../../shared/rules/target-resolution.md"), inline half. Pass MODELOVERRIDE to all Agent() calls via model=MODELOVERRIDE when set. Accepts symbolic names (opus, sonnet, haiku, fable on harnesses whose Agent tool lists it; note fable is premium API spend after 2026-07-12) or full IDs (claude-opus-5-5) per CC 2.1.74. Opus 5.5: Agents use native adaptive thinking (no MCP sequential-thinking needed). Opus 5.5's own effort default is medium, one level below Opus 5's high, and CC 2.1.280+ starts a newly released model at its default, so pass high or xhigh for verification. Extended 128K output supports comprehensive verification reports. --- STEP 0: Effort-Aware Verification Scaling Scale verification depth based on /effort level: Effort Level Phases Run Agents Output ------------- ------------ -------- -------- low Run tests only → pass/fail 0 agents Quick check medium Tests + code quality + security + API compliance 4 agents Score + top issues high (default) All 8 phases + 2.5 visual capture 6 agents Full report + grades xhigh All 8 phases + 2.5 visual capture + cross-file pattern sweep + self-verification pass 6 agents Full report with uncertainty annotations Override: Explicit user selection (e.g., "Full verification") overrides /effort downscaling. …
